The CLI tool should provide all access for everything that LibLyketo provides.
Currently, the tool just decrypts a CryptedObject (MCOZ) and it should be adapter to support more and more functionality.

List of funtionality missing:

• Basic Proto pack and unpack (Perhaps export and import RAW just for test?)
• Basic EterPack pack and unpack
• Configuration of Proto FourCC and XTEA keys, as well as the type of CryptedObject to use during packing.
• Configuring EterPack XTEA keys (when Type2 will be supported), extensions (easy to do), version, FourCC and the type of algorithm to use to crypt the Index file (MCOZ/MCSP).
• Automatic append "d:/" to ymir work, or let the user specify "d_".

The library is only tested under Windows.
Please report any possible building issue while using any other platform.

Implement MCSP Snappy cryptation in CryptedObject and bundle the library / set it as a dependency on CMake.
Either vcpkg could work in this situation? 🤔

While testing the CliApp, there is an heap corruption in CryptedObject.cpp , and it looks to be related to std::vector<uint8_t> data;.

No documentation for LibLyketo include files is being specified. This should be required for allowing the library to be easy to use in the future.

EterPack class currently supports Type0 only. The following types would be required to get a normal support of Metin files:

• Type 1 (LZO)
• Type 2 (MCOZ)

Optionally, for loading official new files the library would need:

• Type 3 (Panama/IV?)
• Type 4 (HybridCrypt)
• Type 5 (HybridCrypt for maps?)
• Type 6 (MCSP)
